nmmr. e. or Los mennm' earn-01mm rrrn-cmaurnennvicn Application filed October 21, 1922. Serial No. 595,958.

To all whom it may concern:

Be it known that I, DANIEIT G. MARKS, a citizenof the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Pipe-Cleaning Devices, of which the following is a specification. v

My invention relates toyand .has for-its" purpose the provision of a device capable of being used for the removal'of sediment and other solid matter from water or' gas pipes, or the training of electrical conductors through condui g It is also a purpose of my invention to rovide a .device of the above described c aracter. which includes a length of resilient wire coiled upon itselfat one end and provided with an obstruction engaging element and scope of the ap apphed position with at the other end, a holder being deslgned for rotatably' receiving the coiled end of the wire to allow of the colling and uncoiling of the length of wire in applying and removing device shown in Figure 1 with the holder in which simi similar parts, my

section.

Referrin specifically to the drawin s, in ar reference characters .re er to invention, inits present embodiment, comprises a single length of resilient wire-15- ofsuitable length'and gauge which is coiled upon itselfat one end, as 1ndlcated at 16, andwith such end secured to the adjacent convolution'as indicated at 17.

15. For receiving the coiled end 16 of the wire e opposite or free end of the wire-15 carrles a member 18 which constitutes an elementzfor removing obstructions from the 1pc, this-element, in the present instance, emg in the form of an elongated coil constructed by coiling the free end of the wire 15 so as to allow rotation thereof in effecting I a coiling or uncoiling of the remainderof the wire, a holder 19 is provided,'such holder, in

the present instance, being in the form of a pipe of substantially seml-circular contour.

The internal diameter of the pipe 19 is such as to not only rotatably receive the coiled end 16 but to remainder of t e wire 15 about the coiled end 16 so that when the wire is not in use it may occupy the coiled position shown in Figure 2.

When employing the device in effecting rmit of the coiling of the the removal of sediment or other solid matfer from a water or gas ipe, the member 18 is inserted into one en of the pipe and forced throu h the pipe in the usual manner, the wire 15 in uncoiled during this operation. When t e proper cleaning of the pipe has beenv efiected, the wire '15 is withdrawn from the ipe, and during such withdrawal the coiled portion of the wire is rotated within the holder 19, thus effecting the coiling of the wire as it is withdrawn from the pipe. This obviously prevents the sediment-covered wire from spreadin to all arts of the room during the remova thereof om. the pi e. During the unwinding of i the coil, it will be clear that by rotating the the wire can be fed coil through the holder into the pipe.

When em loyin the device for training conductors t roug conduits, it will be clear that the conductors can be attached to the Y element 18 after the wire 15 has been trained throu h theconduit, so that by removi the wire" cm the conduit the training 0 the conductors through'the latter canbe efiected. In coiling and uncoilingthe wire during this 0 ration, the holder 19 operates in conjunction with the coiled end of the wire to facilitate the uncoiling of the wire and the recoiling thereof. t-

I claim. as my invention:

1. A device of the character described comprising a length of resilient wire having one end. coiled upon itself and secured "in coiled form, and means for rotatably receiving the coiled end.

2. A device of the character described comprising a; length of resilient wire having one end coiled upon itself and secured in coiled form, and a tubular member of arcuactie form for rotatably receiving the coiled en 3. A device of the character described comprising a coil of wire capable of being partly uncoiled, and a tubular holder having open,

ends for receiving the coil to permit coiling or uncoilingw thereof. 7

comprising a len h of resilient material 5 havin one-end coi 'ed upon itself and secured in coi ed form, and means 'for rotatably receiving' the coiled end.

7 5. A device of the character described comprising a length of resilient wire having one end coiled upon itself and secured 1d v in coiled form, an obstruction-engaging ele' 4. A device of the character describedment on the free end of the wire, and e. semicircular tubular member for rotatablg receivingthe coiled end. A

In testimony whereof I have signed my 15 name to this specification.
